Reaction Steps

To a solution of 4-bromo-6-(((1S,2S)-2-(5-methoxypyridin-2-yl)cyclopropyl)methoxy)-2-methylpyridazin-3(2H)-one (70 mg, 0.19 mmol) in toluene (5 mL) under N2, ((3-ethyl-1-methyl-1H-pyrazol-5-yl)methanamine (32.2 mg, 0.23 mmol), Pd2(dba)3 (18 mg, 0.019 mmol), BINAP (35 mg, 0.06 mmol) and NaOtBu (27 mg, 0.285 mmol) were added. After the reaction mixture was stirred at 100° C. overnight, 15 mL water was added. The mixture was extracted with EtOAc (2×10 mL). The combined organics were dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by Prep-HPLC to give the title compound as oil. 1H NMR (400 MHz, CDCl3) δ 8.43 (s, 1H), 7.73 (d, 1H), 7.21 (d, 1H), 6.14 (s, 1H), 5.75 (s, 1H), 4.45-4.28 (m, 3H), 4.00 (d, 4H), 3.89 (s, 3H), 3.67 (s, 3H), 2.66 (d, 2H), 2.53 (s, 1H), 1.88 (s, 1H), 1.41 (s, 2H), 1.22 (t, 3H).
